Was considering mounting my HD's behind a Kama Bay myself until I saw Tetsu's post above. My PC's airflow was quite bad and the cable management had become horrible... (see below pic)
...so I bought a Lian Li EX-34N to mount in my Mirage case which has made quite a nice difference overall.
Shame about the rats nest at the very top of my case though a fan controller might help alleviate that in the future.
The only small gripe is there is a small gap at the top of the fan grill (see above picture) but otherwise I'm very happy with the results.
Below are some close up pictures of the EX-34N for anyone that's interested in it:
